Long-persistent phosphorescent SrAl₂O₄:Eu²⁺, Dy³⁺nanotubes

Abstract

SrAl(2)O(4):Eu(2+), Dy(3+) polynary complex nanotubes with long afterglow, templated by surfactant assemblies, were successfully synthesized by a homogeneous coprecipitation method, followed by heat treatment in a reducing atmosphere.
